What is the equation presented in Charles's Law?

• A. V1 x T2 = V2 x T1
• B. V1 + T1 = V2 + T2
• C. V1 / T1 = V2 / T2
• D. V1 - T1 = V2 - T2

Answer: (C)

Charles's Law describes the relationship between the volume and temperature of a gas when the pressure is held constant. The correct equation, which states that the volume of a gas is directly proportional to its absolute temperature, is expressed as V1/T1 = V2/T2. This illustrates that as the temperature (in Kelvin) of a gas increases, its volume also increases, provided that the pressure does not change. This relationship is fundamental in understanding how gases behave under varying temperature conditions, which is essential knowledge in fields such as medicine and flight paramedicine. The use of absolute temperature is important because it ensures that the mathematical relationship remains valid throughout all temperature ranges, including when the gas is at its lowest energy state, or absolute zero. In contrast, the other options do not accurately represent Charles's Law. While they may include components of gas laws or relationships, they fail to encapsulate the direct proportionality that is a hallmark of Charles's Law. Understanding this law is crucial for making informed decisions about patient care in clinical settings, particularly in scenarios where gas exchange is involved, such as with respiratory support or altitude changes during flight.
